ANGLE-COUPLIN G.

Patented March 1 7, 1908.

Application filed August a, 1907. Serial No. 386,919.

-- ed to connect two shafts at an angle with relation to each other insuch manner that power applied to one ofsaid shafts will be transmittedto the other of said shafts and to. so' mount this structure that it maybe readily sup orted either. from the floor or from the cel 'ng and willbe kept thoroughly lubricated in either position.

Further objects and advantages of the invention will be set forth in thedetailed description which now. follows.

In the accompan 'ng drawing: Figure 1 is an endelevation o anv 9.11 locoupling constructed in accordance wit the invention, Fi 2 is ahorizontal section upon line 00-90 of ig. 1, Fig. 3 is a detail view ofa bifurcated member carried by one of the shafts illustrating aportionof the casing, Fi 4 is a detail edge view of a con lin mem erhereinafter described, and, Fig. 5 1s a detail view of a bearing blockand the pins carried thereby.

Like numerals designate corresponding parts in all of the figures of thedrawlng.

Referring to the drawing, the numeral 5 designates a-base which isprovided with a flange 6 adapted tobe bolted either to the floor or tothe ceiling. This base sup orts a casing 7 having a flange 8 castintegra therewith. A flange 90f a cap 10 is adapted to be secured bybolts 11 to the flan e 8 of the casi 7. This casing is adapte to contain911 w ch will be splashed over the mechanism contamed within the casingby the rotation of said mechanism and to provide means for indicatingthe quantity of oil contained withih the casing at any time, the ipes 12will always be indicated within the are connected with the casin an witha slght or gage lass 13. It wil therefore be seen that the eight of oilwithin the casing, lass whether the flange 6 be bolted to the oor or tothe ceiling.

Bearing sleeves 14 are cast integral with the casing and providebearings for a drive shaft 16 and a driven shaft 17. Cups 18 are drivenupon the shafts 16 and 17 with so tight a fit that no oil can passbetween them and the shafts. These cups project into sleeves 19 and oilducts 20 lead from the interior of these sleeves to the interior of thecasing both above the shafts 16 and 17 andbelow said shafts, wherebywhether the easing be in the osition shown in Fi 1 or 0t erwise as w enthe flan e 6 is b0 ted to the ceiling, an oil duct wil lead from thelower portion of the sleeves 19 to the-interior, of the casing andreturn any oil that asses into the sleeves l9 fromsaid casing. he shafts16 and 17 carryat their inner ends the bifurcated or forked members 21,said members being provided with hearing bosses 22 which serve a purposehereinafter described. These forked members 21 of the shafts 16 and 17are connected by a member 23-. This connectingmelnber 23 is forked ateach end and is provided with bearing bosses 24 u on the extremity ofeach of said forked portions. Blocks 25 lie between the forkedextremities of the member 23 and between the forked members 21. Bearingpins 26 are formed integral with these blocks.

As is best illustrated in Fig. 4, the member 23 is made in two parts andis secured together by bolts 27 and nuts 28.

In assembling the parts, the blocks 25 are placed in position with thepins 26 resting in the bearing bosses 24 of one of the halves of member23. The other half of the member 23 is then placed imposition and thetwo halves are secured in position by the bolts and nuts as hereinbeforeset forth. This secures the pins 26 within the bearingbosses 24 of themember 23, said pins being freely rotatable in said bearings. The member23 is then moved into such position as to bring the blocks 25 betweenthe forked ends of the members 2] after which pins 29 are driven throughthe bearing bosses 22 and through the blocks 25, said pins being freelyrotatable in the bearing'bosses 22 and being held secure] in the bearingblocks 25b pins 30 whi aredriven through the blocks 25 and which piercethe pins 29. The structure'of the blocks 25 and the arrangement of thebearing pins is clearl illustrated in Fig. 5. It has been found t at indevices of this character where the s lashing of the oil upon the partshas been rehed upon for lubrication therefrom by said centrifugal forcewithout the oil away from the bearings rather thanupon the bearings. Theoil is s lashed upon the moving parts, but is immedlately thrown orderto accomplish this, I form in the with o tofore been destructive of afaces of the blocks 25 oil cups 31 having undercut walls. Ducts 32 leadfrom theseoil cups to the bearing pins 26 and 29 and from opposite facesof, the blocks. The rotation o the ]parts when the casing is partlyfilled splashes the oil about, some of said oil falling mto the cups 31and being thrown through the ducts by centrifugal force to the bearingpins 26 and 29. seen that I utilize the force which has herero erlubrication with a splash system of 0' ing, to accomplish a proper andefficient lubrication. Any oil passing through the sleeves 14 and aboutthe shafts 16 and 17 will enter the cups 18. Since the driving fitbetween these on s' and said shafts renders it impossible for t e oiltopass out between the cups and the shafts, the only path for the oil isaround and over the outer faces of the cups. These outerfaces areannularly ribbed as at 32 and when the oil reaches these annular ribs,it is thrown offb centrifugal force into the sleeves 19, fin ing its wayfrom these, sleeves through the ducts 20 to the interior ofthe casing. aI

From the foregoing description, it will be seen that simple andefliclent means are herein fprovided for accomplishing the objects o theinvention, but while the elements shown-and described are well adaptedto serve the purposes for which they are in-' tended, it is to beunderstood that the in- A more readil ing from said oil pockets to thebearing mem:

It will therefore be 1. In a device of the character described thecombination with a block of a plurality of bearing members carried bysaid block, said block having oil ockets formed therein, thewalls ofsaid poc ets being under-cut .to

retain the oil and oil ducts leadbers.

2. In a device ofthe character described the combination with a forkeddriving mem ber, of-aforked driven member, a connecting member, forkedat each end, a block ada ted toenter between the forked portions 0 thedriven member andthe forked portions of the connecting member at one endof said connecting member, bearing members carried by said block andadapted to engage the forked portions of the ving member and the forkedportions of the connecting memher, a second block adapted to enterbetween the forked ortions of the driven memberand the for ed portionsof the connecting member at the opposite endof the connecting member,bearing members carried b 'said block and adapted to engage said 'venmember' and said connecting member, there being oil der-cutwalls formedin thfaces of said blocks and ducts leading from' said oil pockets tosaid bearing members. c
